Programming a 35 options menu in a batch file - batch-file

Question

The following batch file works perfectly for the first 10 options. However I do not know how to extend the functionality of the batch file more than 10 option 0- 9. I have 35 possible options.
#ECHO OFF
MODE CON:COLS=100 LINES=50
SETLOCAL ENABLEEXTENSIONS DISABLEDELAYEDEXPANSION
(SET sourceFolder=C:\Users\Administrator\Desktop\test)
](SET targetFolder=C:\Users\Administrator\Desktop\test2)
SET /P "customerID=Enter Customer ID: "
:MENU
CLS
ECHO=
ECHO= ..................................................
ECHO= PLEASE SELECT THE OPTION FROM THE EVENT MENU BELOW

Answer 1

Took me some time to understand what your problem was:
when you type a choice, you get the index of the choice and not the relevant letter, making it impossible to link back to the selected item of the menu if not 0-9.
So I propose to convert back your index to the entered letter like this (extract):
SET "Option=%ERRORLEVEL%" <== this is your code
rem here scan for correct letter
FOR /L %%a IN (0,1,35) DO if %%a==%Option% set idx=%%a
rem small correction of index
set /A idx-=1
set Option=!Choice:~%idx%,1!
Full test code, pressing a digit or a letter prints the letter and the code & title of the menu:
#echo off
set CHOICE=0123456789ABCDEFGHIJKLMNOPQRSTUVWXY
SETLOCAL ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION

SET "Option=%ERRORLEVEL%"
rem here scan for correct letter
FOR /L %%a IN (0,1,35) DO if %%a==%Option% set idx=%%a
rem small correction of index
set /A idx-=1
set Option=!Choice:~%idx%,1!
FOR /F "TOKENS=1-4 DELIMS=. " %%A IN ('FINDSTR/BC:"ECHO. " "%~f0"'
) DO (IF "%%B"=="%Option%" (SET "Name=%%C" & SET "Code=%%D" & echo activated %Option%: !Name!,!Code!)
)
Notes:
I needed to enable delayed expansion back
I set CHOICE in a variable at the start, nicer to propose the choice and then scan into it for correct letter/digit

Answer 2

May I suggest a different approach based on arrays that run faster and is simpler to keep updated?
#ECHO OFF
MODE CON:COLS=100 LINES=50
SETLOCAL ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
(SET sourceFolder=C:\Users\Administrator\Desktop\test)
(SET targetFolder=C:\Users\Administrator\Desktop\test2)
SET /P "customerID=Enter Customer ID: "
REM Assemble the data arrays
set i=0
set "options="
FOR /F "TOKENS=1-4 DELIMS=. " %%A IN ('FINDSTR/BC:"ECHO. " "%~f0"') DO (
set /A i+=1
set "options=!options!%%B"
SET "Name[!i!]=%%C"
SET "Code[!i!]=%%D"
)
